Be it known that I, CARL A. J oHANNnsnN, su ect i'f'. 1 ;liv King of Norway, residing yat yn, inthe county of Kings and State of New York, have, invented certain' new i and useful Improvements, in Projectiles, of

which the following is a specification. ,j

Myinvcntion relates to ammunition and'y explosive. devices, and more particularly to an improved form of projectile for use in mss-sm i e primary provide a projec e and is of e which aifords a longer a greater power than the manner. l

ao gun als ' drawings, in which,

of the ments of my invention,

` 'similar parts 'ingle main opening 4 for a purposewhi ap ear.

'F' 2 'is a longitudinal sectional view ofthe lighting head pr e losive -bul1et.

Fi 311s a similar view o the shell having head removed. l

transverse sectional view taken Fig.'1 looking inthe elevational view of.

the ghting Fi e isa on t e line 4 4 of direction of the arrow', F 5 is a front end the ell.

Similar reference characters designate throughout the various views fth drawings.' 4- o e I have illustrated -my In the drawings, improved proj 'tile as preferably embodyi l 1 open at one en casing or she provided with a plurality of tortuous face. The

ves 2 oii its inner peripheral rear end of the shell. is closedz as closing end wall being provided with an The iig ting 4head or bullet includes .a y or shell 5 substantially cylindricalin cross section and, having a plurality of tor# ob ect-of "invention -is to td y ' device d such strength tuous tongues 6 on its outer peripheral face for engagement in the grooves 2 formed in the she l 1. The forward end of tlieshell 5 is enlarged and tapered to provide a penctrating head 7, said enlar d striking head having a shoulder 8 at its ie ythe movement of the bullet 5'into the main shell 1. The' shell or bullet 5 is of a length which when inserted into the shell -1 will" alici-d a charge receiving' chamber 9 in the ase which limits rear thereof,.said chamber being filled with antexplosive charge 10 of any desired com ositioii. *A time fuse 11 leads to said chamber 4and is adapted to be ignited when the projectile is initially started on its flight. ,The bullet or shell 5s filled with an explosive comosition 12 which 'is adapted to be explo .when the head 7 strikes an object and the iii-ing mechanism may' employ the usual detonatin cap and mechanism therefor.

This mec anism is indicated orally b the numeral 13. The front en of the she l 1 may be beveled, as indicated at 14 so that when the bulletand shell are assemliled the resents an outward appearance practica 1y identical. withthat of the usual form of projectile` In use, -the projectile is placed in the breech of a gun' and the usual charge of smokeless powder inserted behind the same. The breech of the gun is closed in the usual manner and the shell having the'bullet 5 t be launche on its iii ht. In the initial discharge of the lgun the use 11 is lighted and .when the fuse urns into the e losive composition 10 the latter will be exp oded sending the bullet 5 farther than the original discharge. The grooves 2 and the tongues 6 must be formed so that when the bullet is dischar ed from the shell 1 a twistin motion will e given to said bullet and o course these groovesand tongues must be oppositely arranged to the initial twisti motion given by the gun. Attention is c ed to' the fact that the charge 10 of explosive material must be of as will not 'overcomethe momentum o the shell 1 but will utilize'the shell in its forward Biht as a It 1s of course to be understoo that the proportionof charges to be used as well as the timing of the fuse 11 may be developed when using the device in actual practice. c

From the above description taken in connection with the accompan drawing it is thought that a clear and mprehensive the powder is exploded causin n nd advantages of m readily gathered, and w ile I have shown and described the same as' emhodying e, s' ecili'c' structure I desire that it be understoo tlit I may ineke such chen es therein which do not depart from the splrit and scope of the inventlon as claimed.

IV claim; y; A In a projectile of the class` described, a. csing openat one end and closed-et the other ancl provided with a plurality of oppositely disposed spiral grooves o n its 4inner peripheral face, said grooves entendi ing Ifvrornseid open end nwardlyfa, time. fnseextending into said casing through: the closed end thereof, a. shell mounted in said easing and includin a body portion having arsolid cone-shaped earl with e laterally extending shoulder at its base ro'ecting be ond said body portion, said hell also hav- 'i mgv a plurality of oppostely disposed spiral Ashell body 'casing to prove `an explosive chamber f1` empi-1 ribs extending from said shoulder toward its opposite end and positioned to engage the ooves of saidy casing, said shell having itsv dy :tion snugly fitting 'withnthe easingI wi the shoulder at the base Iof ite head abn theopen end oftlxecasing,

lin of less length than seid the rear of the shell when the parte are 'as '1 sembled, an ex'plosve charge in said cham ber, an explosive charge in the s hell, cletonating cap \in said shells endo lirlng ro;

extending throu hthe a en of said shell head-and adapte to coperatie with'seid cap to ignite the char within the shell.
